摘要
为了研究空芯反谐振光纤的中红外激光传输能力,使用自制的无节点空芯反谐振光纤进行了2.60~4.35μm的中红外激光传输实验。该空芯反谐振光纤包层由七根平均壁厚为800 nm的玻璃毛细管组成,光纤外径为365μm,纤芯直径为115μm。使用中红外可调谐光参量振荡器作为光源,测试了光纤在2.60,3.27,3.41,3.80,4.08,4.21,4.35μm七个波段的激光传输及损耗特性。结果显示,该光纤可实现2.6~4.08μm波段低损耗导光,在3.27μm传输损耗最低,为0.037 dB/m。光纤在4.08μm和4.35μm处的传输损耗分别为3.200 dB/m和0.788 dB/m,而该波段熔融石英吸收损耗分别高达1000 dB/m和3000 dB/m。研究结果证明,空芯反谐振光纤在中红外激光柔性传输领域拥有巨大潜力。
To study the transmission ability of hollow-core anti-resonance fiber,a mid-infrared laser transmission experiment was carried out using a self-made nodeless hollow-core anti-resonance fiber from 2.6μm to 4.35μm spectral region.The fiber cladding consists of seven silica capillary tubes,the average wall thickness is 800 nm,the outer diameter of the fiber is 365μm,and the core diameter is 115μm.A tunable mid-infrared source was used as a broadband light source.The laser propagation capability of the fiber at 2.60μm,3.27μm,3.41μm,3.80μm,4.08μm,4.21μm,and 4.35μm was tested.And the transmission loss at this spectral region of the fiber was measured.Results show that the fiber can realize low-loss light guide from 2.6μm to 4.08μm band,with the lowest transmission loss of 0.037 dB/m at 3.27μm.The transmission loss of the fiber is 3.200 dB/m at 4.08μm and0.788 dB/m at 4.35μm,where the attenuation of bulk silica is 1000 dB/m and 3000 dB/m,respectively.Hollowcore anti-resonance fiber has great potential in the application of mid-infrared laser flexible delivery.
